And Car B came in from 472 and for whatever reason, is now about to make a complete turnaround, heading the other way on 472, and therefore has to go ALL the way around the circle - and obviously that means he has to cross those dotted lines to get to the inside lane because if he stays in the right lane, he would be required to go north on Buena Vista, and wouldn't be able to complete his turn.

Both cars have just entered from their perspective sides. But perhaps there's a car in front of Car A, so he is going a little slower, and car B gets onto the roundabout RIGHT when car B finally starts speeding up. Then BOOM. Accident at the southbound lane, because according to those arrows, each of them has the right to be where they are.

Obviously this kind of thing (similar, not necessarily the exact same thing) happens - because if it didn't, there wouldn't be so many pages on so many threads about it. There wouldn't be article after article over the years about fender-benders (and worse) on these roundabouts.

Regardless of "who is doing it wrong" the fact remains: these roundabouts are NOT clear and simple and effortless. Stop signs and street lights are clear: red means stop, green means go, yellow means slow and prepare to stop. Roundabout means go this way, unless you want to go that way, and get in this lane, unless you need to get in that lane, and never enter from this thing, and don't cross over that thing, but none of this matters if you're on THOSE two roundabouts because they're different.

This is WHY there are pages upon pages on threads upon threads and articles upon articles about the problems. Because it is NOT clear. It is not effortless. It is not simple. And you're dealing with a whole lot of people in death machines who ALL think they're doing it right.

No, you have to know the meaning of stops sign and legally where to stop especially at 4 way stops and know what yield sign means and how it applies to intersection
